FIRE-ESCAPE.

SPECIFICATION forming part of Letters Patent N 0. 660,674. dated October30, 1900. Application filed November 22, 1899. Serial No. 737,890. (Nomodel) To all whom, it nuty concern:

Be it known that I, LOUIS WEBER, a subject of the Emperor ofAustria-Hungary, residing at Uj-Verbasz, Austria-Hungary, have inventedcertain new and useful Improvements in Detachable WVindows for SavingLife in Case of Fire, of which the following is a full, clear, and exactdescription.

According to the present invention the window with the frame or sashforminga box-like whole is not fixed in the wall of the building, butmay be removed easily therefrom and let down to the ground by suitableropes or wires or the like, so that in case of fire persons living inthe upper stories may release the window from the wall and gradually letthe same down to the ground after having seated or otherwise securedthemselves in the frame.

In order to render the present specification easily intelligible,reference is had to the accompanying drawings, in which similar lettersof reference denote similar parts throughout the several views.

Figure l is a side elevation showing the Window-frame in position in thewall and the surrounding parts of the wall in section. Fig. 2 is a partfront elevation of the window; Fig. 3, a plan of the window-frame withthe adjacent wall parts in section, and Fig. at a perspective partelevation showing the position of the arms when the window is beinglowered.

According to one form of carrying out my invention one or more pairs ofarms 9 h and g h are pivot-ally attached at cl d at each side of thewindow-frame and provided with guiding-segments ff, which limit theirmovements around the pivot, so that when in operation the said arms willextend horizontally from the window-frame, Fig. 4E, and keep the same acertain distance up from the wall, so that the window when lowered willrun clear of obstacles on the wall, such as facings and the sills ofwindows below. The said windowframe a, is supported at either side bymeans of cords or wires 0, fixed to a point e e on the said arms somelittle distance from the pivots d d of the same. If more than one pairof arms is employed at either side of the window, (two pairs are shownin the drawings,) the second pair g h is mounted below the first, andthe cord is attached to one member g of the lower pair at e and taken upthrough an eye 6 on the corresponding member 9 of the upper pair. Thetwo cords 0, one at either side of the frame, are then wound around adrum b, mounted on a shaft Z, mounted above the window, which is alsoprovided with a counterpoise m, having cord b, which winds up as thewindow-cords unwind, and thus prevents a too-rapid movement of the saidwindow downward. One membergg of each pair of arms is longer than theother it h and provided with a hooked or bent round end, Fig. 4, adaptedwhen the window is lowered to engage a guide-groove j, extending downthe front of the wall of the building, while the shorter member isprovided with a foot It, which rests against the face of the wall andforms a supporting arm or strut for the said hook after the manner of abracket-support. On lowering the window the hooked arm at either side ofthe same may be placed in the open upper end of the groove or railj.(See Fig. 4.)

The whole window-frame is supported on rolls t' t, mounted beneath thebottom or sill of the frame, and may be retained in position in the wallwhen not required to be lowered by any suitable means which may beeasily disengaged. In case of fire the said fastening may be disengaged,the window will roll out of its seating in the wall, and the cords beingstretched by the weight of the frame will pull the pairs of arms 9 h git around into the horizontal position, the hooked arms 9 g will engagethe guide-groove, and the somewhat-shorter arm h h of each pair willfall slightly below the hook of the longer arm and, resting with itsfoot against the face of the wall, will stay or support the whole frame.The person may getinto the windowframe and work himself gradually downto the ground, the counterpoise serving to prevent too-rapid descent.

I claim as my invention- 1. The combination of a Window having awindow-frame detachably mounted in the wall, means for suspending saidwindowframe, and lateral lever-arms mounted at each side of the saidframe and means for projecting them forward when the window is lowered,to retain the said frame the required distance from the front of thehouse substantially as described.

2. The combination of a window and frame detachably mounted in thewall,two pairs of arms pivotally mounted one above The other at each side ofthe said frame, cords at each side of the window and drums mounted abovethe window onto which said cords are Wound, the said cords having theirends attached to the longer hooked arms of each pair atsuitable'distance from the pivot, and means at the front of the buildingto guide the said IO hooked arms, and a foot 70 to the shorter arms toserve as a strut substantially as described. In witnesswhereof I havehereunto set my hand in presence of two witnesses. I

V LOUIS WEBER.
